"New Physics Searches using Jet Substructure with the CMS Experiment"
 Slideshow (PDF)

Many searches for new physics at the LHC involve decays to heavy objects such as W, Z, and Higgs bosons, or top quarks.  I will present the latest algorithms to identify hadronic decays of these objects at high momentum, where decay products may overlap in the detector.  These jet substructure algorithms aim to efficiently identify distinct topologies of particles within a jet, while simultaneously rejecting the large QCD backgrounds.  I will show the latest results from CMS searches for new physics using these signatures, including searches for top quark pair resonances and vector-like top and bottom partner quarks.  Looking toward the future, I will also discuss some new developments in the field of jet substructure being considered for new analyses.
